I have been trying a few pellets through mine this morning ready for a trip out mid-week. I can only go out to 20yrds in my garden, but I have now tested over 15 different pellet makes. So when you get yours, you could do worse than to start with these:- (In order of accuracy through my rifle).
1) JSB exacts (4.53mm/8.44gr) = (I shot 5 x 5 shot groups UNDER 8mm today) - best was 6mm group.
2) H&N FTT (4.50mm/8.5gr) = Averaging 9mm groups - best was also 6mm.
3) Weihrauch F&T specials (4.51mm/8.7gr) = also averaging a little over 9mm from 5 groups of 5 - best was 7mm
4) RWS supe
